Staff Software Engineer, Full Stack

## About the role Field sales powers the economy — but most teams are struggling. Reps are buried in admin work, managers are stretched thin, and leaders can't see what's really happening in the field. Siro is redefining how field sales teams learn, perform, and win. We started as an AI-powered coaching platform that helped reps improve their outcomes in the field. Today, we're something much bigger — an intelligent companion that automates sales reps' tedious admin work, gives managers real-time visibility, and helps executives see around corners. Our platform integrates with systems like Salesforce, analyzing thousands of in-person sales conversations to surface insights, automate workflows, and drive better outcomes across the org. Think Iron Man's Jarvis for sales — proactive, personalized, and built directly into the tools teams already use. Siro has raised $75M and is backed by world-class investors like Index, Fika, CRV, and SignalFire. We are trusted by leading home-improvement, retail, hospitality, and automotive brands, and powered by a lean team from Meta, McKinsey, Doordash, and Uber.
